'IMPROVEMENT IN HANGERS FOR SHAFTING.

Specification forming part of Letters Patent No. 137,593, dated April 8,1873; application filed March 15, 1873.

To all whom it may concern:

Be it known that I, WILsoN W. CAREY, of Lowell, of the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Hangers or Shaft-Box Supporters and do hereby declare thesame to be fully described in the following specification andrepresentedin the accompanyingdrawing, of which Figure l is a front elevation, Fig.2 a side view, Fig. 3 a longitudinal section, and Fig. 4 a transversesection, of one of my improved hangers with a single cross-head.elevation of one with two crossheads.

My invention has reference to the box, its oilingdevices, and the hangeror support of the box.

In the drawing, A denotes the journal-box, the middle part a of which isglobular and rests on a correspondingly-concave saddle, B. On the top ofthe part a is a concave washer, b, which is held down upon the part a bya screw, 0, that screws down through the cross head 0 and is providedwith a check-nut, d, all as represented. The saddle B and the crossheadC are supported in their relative positions and in their connection witha cap, D, by means of two wrought-iron screw-bolts, E F, extendingthrough and downward from the said cap, in manner as shown. bolts gothrough the cross-head and the saddle,.and are furnished with malescrews 6 a to receive nuts f f, g g, and h h, arranged upon the screws,and with respect to the saddle and cross-head, in manner as represented.The

cap D, the cross-head C, and the saddle B are to be of cast-iron. Thecap is to be secured to the ceiling or flooring by means of screws goingthrough the said cap. The box, formed and Babbitted in the usual manner,or as shown, has a long slot, 70, made longitudinally in its upper part,to receive the educt l of an oiler. This Fig. 5 is an The two' educt isa tube closed at its two ends and slotted lengthwise on its under sideto receive a strip, m, of leather, the slot being dovetailed intransverse section. Leading upward from the educt are two tubes ortubular branches, n a, each of which is surmounted by and leads out ofan oil-receiver, 0. There may be but one of such oilreceivers andbranches to the educt; but I prefer to use two, on account of oneserving to balance the other end to keep the leather of the eductdulypressed throughout its length down upon the journal when in the box.

The oil, passing into the educt, will flow therefrom through the stripof leather and upon the journal while it may be in revolution.

When a longer hanger may be required, two or more of the cross-heads maybe used with bolts of the necessary length, such a hanger beingrepresented in Fig. 5.

The mode of constructing the hanger renders it very strong and durable,the crosshead, with its screw, serving to maintain the box upon thesaddle, and to allow of it working or accommodating itself to themotions of the shaft.

I claim- 1. The hanger, as composed of the cast-metal cap D, cross-headC, and saddle B, and the two wrought'iron screw-bolts E F, with theirnuts ff, g g, and h h, all constructed and arranged substantially as setforth.

2. The box slotted at top, as described, and the tube or educt Z,arranged in the slots is and connected with one or two oil-reservoirs,0, all substantially as explained.

- WILSON W, CAREY.
